The Indian purple frog (Nasikabatrachus sahyadrensis) is a unique burrowing frog that spends most of its life underground. It is so different fro all other frogs that it belongs to a family of its own. The Indian purple frog is able to spent eleven months in a burrow, has a small distribution range and is critically endangered. It is restricted to the Western Ghats complex of Southwestern India, a known biological diversity hotspot.
Nasikabatrachus looks like a squat, grumpy blob. Some even compared it to a bloated doughnut with stubby legs and a pointed snout. However, this creature is tough enough to survive almost unchanged for 150 million years.
A direct threat to Nasikabatrachus sahyadrensis in the form of collection for human consumption of its tadpoles by tribal or indigenous
communities dwelling in and around forest areas of Kerala state. Human consumption of purple frog tadpoles is an old practice amongst the local tribal people.
